In this study, a field experiment was conducted at the Minqin Experimental Station of the Gansu Institute of Hydraulic Sciences between 2016 and 2018 to investigate the influence of dual mulching with crushed wheat straw padding and plastic film combined with different irrigation amounts on soil nutrients and the growth of edible sunflower. The experiment was conducted using a two-factor design with four mulching methods and three irrigation levels. The results of the study revealed that the soil nutrients under the dual mulching of crushed wheat straw padding and plastic film showed significant improvement. The soil nutrient status showed a significant improvement by mulching in comparison with no mulching, and the dual mulching of crushed wheat straw padding and plastic film gave the best results compared to other mulching methods. The medium irrigation level shows better soil nutrient improvement as compared to other irrigation levels. The results obtained from the current experimental study in the Minqin oasis area with drought and little rain revealed that edible sunflowers can be grown under the dual mulching method of crushed wheat straw padding and plastic film as an optimal conservation tillage method.
The Ocean Plastics Charter aims to bring together leading countries, sub-national governments, businesses, and civil society organisations to commit to a more resource-efficient and sustainable approach to keep plastics in the economy and out of the environment. With this charter, it aims to transition to a more sustainable and resource-efficient method of managing plastics. Through[…]
These regulations are intended to promote sustainable development, food security, and the sustainable management of fishing activities in Palau’s waters. They also intend to create economic returns, employment generation, and export earnings from the sustainable harvesting of tuna and tuna-like species by encouraging the development of domestic fishing industries and a local tuna market. These[…]
This subchapter E of Title 40 of the Code of Federal Regulations outlines the pesticide programs, including registration and classification procedures, policies, special review procedures, standards, labelling requirements, packaging requirements, data requirements, and good laboratory practice standards. It also covers state registration of pesticide products, rules of practice governing hearings under the federal Insecticide, Fungicide,[…]
The Plastics Roadmap aims to decrease littering and other environmental harm brought on by plastics, prevent needless use, enhance plastic recycling, and replace traditional polymers derived from fossil fuels combined with various substances and liquids. To guarantee more focus on sustainable product development, reuse, product recyclability, and the growing usage of recovered plastics, these objectives[…]
The regulations aim to enhance aquaculture pollution prevention and control, protect aquatic ecosystems, ensure product quality and safety, and promote sustainable development. They consist of 24 articles divided into four sections: general provisions, delimitation of prohibited areas, pollution prevention and control, and environmental monitoring and supervision of fishery waters.
